Subject: [TF-M] Secure Enclave solution in TF-M

Dear All,

Following the tech forum presentation (back in 6^th August) I uploaded the draft design document for the Secure Enclave topic:

https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5653

I also updated the first implementation of the proposed solution for the Musca-B1 board with minimal features, marked as WIP:

https://review.trustedfirmware.org/q/topic:%22Secure+Enclave%22+(status:open%20OR%20status:merged)

Limitations, missing features, notes:

No support for isolation level2 on SSE-200
Protected Storage is an Application RoT partition, but PS also moved to Secure Enclave
Some regression tests running on secure side of SSE-200 fail as all messages are forwarded with the same client ID to Secure Enclave
All IPC message forwarding is a blocking call
Only one message is put into the mailbox at a time
Musca-B1 related documentation is not complete yet
Generated files are not committed, manifest parser should be run before build.
The BL0 component mentioned in the tech forum presentation is not uploaded, as it is based on the new cmake system, and not so interesting right now
Cmake changes are rudimentary, will be rebased to new cmake system.

Any feedback very welcomed!

Best regards,
